From the introduction: This is a Blade Runner hack for Trollbabe. You need the original Trollbabe rules where you can read about the basic game mechanics. Tears in Rain is not a game about re-enacting Blade Runner or repeating all the cool stuff from the movie. That’s been done. It’s about dealing with a situation, and exploring that situation through your own Blade Runner character. Feel free to invent new awesome technology like the Voight-Kampff machine or the Spinners, and give them new cool names and functions. Help the humans. Or help the Replicants. Or try to negotiate between them. Fall in love. Have sex. Solve crimes.
